SUMMARY It is a primary object of the present invention to provide a twopart carton or case including a tray section which, after filling, willfunction as a storage section until the contents are ready to berepacked or labeled and sealed for shipment by application of the lidsection thereto, all of which can be accomplished with a minimum oflabor and without damage to the carton sections.

Another object of the invention is to provide a carton wherein the trayand lid sections may be of different colors and printed each in twocolors different from the two colors of the other section, utilizing asingle two color press.

A further object of the invention is to provide a two part carton thesections of which may be of different strengths as, for example,comprising one section formed of a heavier cardboard than the other orof a different number of plies.

Still another object of the invention is to provide a carton havingwalls of different thicknesses or plies to provide maximum stackingcharacteristics at a minimum of cost, and which eliminates flap waste inthe top and bottom as in top and bottom opening conventional containers.

Another object of the invention is to provide a lid having abutting walledges to substantially increase weight sustaining strength of theassembled case.

Various other objects and advantages of the invention will hereinafterbecome more fully apparent from the following description of thedrawings, illustrating presently preferred embodiments thereof, andwherein:

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring more specifically tothe drawings, and first with reference to FIG. l, the two piece cartonor case as disclosed therein is designated generally 12 and includes abottom or tray section 13 and a cover or lid section 14. The tray 13corresponds with the tray A of application Ser. No. 158,454, heretoforereferred to, including side walls 15 having inturned flaps l6 and endwalls 17 which are secured to the outer sides of the flaps l6 and whichterminate substantially below the upper edges of the walls 15 and flaps16. The walls 15 and 17 rise from the flat tray bottom, now shown inFIG. 1. i

The lid 14 includes a top wall 18, side flaps l9 and end flaps 20. Theend flaps are illustrated as being wider than the side flaps l9 and of awidth such that their bottom edges will abut the upper edges of theflaps 17 when the lid 14 is applied to the tray 13 and its top wall isresting on the upper edges of the walls 15 and flaps 16.

The tray 13 is shown filled with receptacles 21 having upper surfacesdisposed in the same plane as the upper edges of the walls 15 and flaps16. However, receptacles or contents 21 could terminate below the upperedges of the walls 15 and flaps l6 and the assembled case 12 could stillbe stacked, as the lid or top 18 would still be supported by the tray13. The flaps 19 are adhesively secured to the outer sides of the walls15 and the flaps 20 are similarly secured to the flaps 16 by anadhesive, not shown, in the same manner as disclosed in application Ser.No. 158,454.

FIG. 2 illustrates a slightly modified embodiment of lid, designatedgenerally 22, having end flaps or walls 23 which are wider than the sideflaps or walls 24.

FIG. 3 shows a modified tray 25 having end walls 26 which are wider thanthe side walls 27 thereof. The end walls 26 have end extensions formingflaps 28 which are separated by slits 28' from the walls 27 and whichare secured to portions of the inner sides of the walls 27, in the samemanner that the flaps 16 are secured to the walls 17.

The lid 22 can be utilized with the tray 25 and the end walls 23 can beadhesively secured to the outer sides of the end walls 26 to form acarton having end walls of double thickness for increased stackingstrength. The side walls 24 are adhesively secured to portions of theflaps 28 and have their bottom edges abutting the side walls 27, whenthe top portion 29 of the lid is resting on the upper edges of the endwalls 26 and flaps 28.

FIG. 4 illustrates the corner of a tray 30, such as the near corner ofthe tray 13 of FIG. 1. The tray 30 differs from the tray 13 only in thateach of its side walls 31 is of twice the width of the wall 15 and has amedian fold line 32 enabling its upper half 33 to be folded downwardlyand inwardly against the lower half thereof and to be secured thereto inany conventional manner, not, shown, as by an adhesive.

FIG. 5 is a similar view of another embodiment of the tray designatedgenerally 34 which differs from the tray 30 in that the upper half 35 ofeach side wall 36 is folded outwardly and downwardly against the bottomhalf thereof and is likewise adhesively secured thereto.

The tray 37 of FIG. 6 differs from the tray 34 in that each side wall 38thereof has two longitudinal fold lines 39 and 39' and is foldedlongitudinally to provide three plies 40, 41 and 42. The median ply 41is folded outwardly along the fold line 39 and secured against the ply40 which rises from the tray bottom; and the upper or outer ply 42 isfolded upwardly along the fold line 39' and is secured against the outerside of the ply 41. The plies 41 and 42 could be initially securedtogether and could be folded inwardly along the fold line 39 in the samemanner as the ply 33 of FIG. 4 and secured to the inner side of the ply38.

In each of FIGS. 4, and 6, the corner flap forms an extension of onlythe bottom ply of the side wall which rises from the tray bottom.

FIG. 7 illustrates a corner of a lid 43 having an end wall 44, similarto the end wall 26 of FIG. 3, but which is of double width and foldedalong a median line 45 to provide an inner ply 46 which is foldedinwardly and upwardly and secured against the inner side of the wallextensions 68 are folded inwardly and adhesively secured, along withsaid flaps, to the tray walls. The flaps 67 could obviously constituteside flaps and the flaps 70 end flaps.

FIG. 11 illustrates a corner of another embodiment of lid, designatedgenerally 73, having an end flap 74 and a side flap 75. The flap 75differs from the flaps 62 of lid 56 in that it is of the same width asthe flap 74.

Y The flap 75 has beveled ends 76 each extending 44. The wall 44 couldconstitute one of the side walls I rather than one of the end walls ofthe lid 43.

FIG. 10 illustrates a corner of another lid, designated generally 47,having an end wall 48 of triple width as compared to the end wall 26 andwhich is folded along two longitudinal fold lines 49 and 50, so that anintermediate ply 51 thereof abuts the outer side of the ply 52 and isdisposed between said ply and the outer ply 53. The plies 51, 52 and 53may be secured together by an adhesive. The wall 48 could constitute oneof the side walls rather than one of the end walls of the lid 47.

FIG. 8 illustrates another embodiment of the case or carton, designatedgenerally 54, including a tray 55 and lid 56. The tray 55 differs fromthe tray 13 of FIG. 1 only in that its end walls 57 are the same widthas its side walls 58 and the end flaps 59 thereof, so that the upperedges of the walls 57 and 58 and flaps 59 are disposed coplanar.

The lid 56 differs from the lid 14 in that its end flaps 60 are of awidth corresponding to the width of the walls 57 and 58, so that whenthe top wall 61 of the lid is resting on the upper edges of walls 57 and58 and flaps 59 and the flaps 60 are adhesively secured against theouter sides of the end walls 57, said flaps 60 will combine with thewalls 57 to providea carton having end walls of double thickness forincreased stacking strength.

The lid 56 has narrower side flaps 62 which differ from the side flaps19 in that the flaps 62 have beveled ends 63. The lid 56 also differsfrom lid 14 in that the end flaps 60. include extensions 64 which areinturned and which have beveled upper ends 65 which abut the beveledends 63 when the flaps 62 and 64 are secured to'portions of the outersides of the walls 58 by the adhesive coating 66. The abutting flapedges 63 and 65 materially enhance the weight sustaining strength of thecarton 54 for the purpose of stacking.

FIG. 9 illustrates a slightly different embodiment of lid, designatedgenerally 66, including end walls 67 having extensions 68 provided withbeveled inner edges 69, and side walls 70 having beveled end portions71. The adjacent edge portions 69 and 71 of the extensions 68 and flaps70 will assume abutting engagement with one another when flaps 67 and 70are folded to assume positions perpendicular to the top 72 of the lidand the throughout a part of its width from the lid top 77. The flap 74has end extensions 78each having a beveled upper edge portion 79 whichabuts flush against the beveled edge 76, when the flaps 74 and 75 andextension 78 are adhesively secured to the outer sides of the side andend walls of a tray, to provide the added stacking strength heretoforedescribed. The flap 74 could 'obviously constitute one of the side flapsand the flap 75 one of the end flaps.

Conventional cartons and'cases containing cans become enlarged whenstacked due to the can rims impressing the case walls against which theyare disposed. The compressed wall areas cause said walls to becomeenlarged so that the cans are loose in the carton or case after the casehas-been opened for labeling or repacking the cans and rescaled. Withthe cartons or cases 12 and 54 of the present invention, the lids arenot utilized while the unlabeled cans are in storage and whensubsequently applied, after labeling or repacking of the cans, the lidwill draw in the side and end walls of the enlarged tray when sealedthereto to provide a carton in which the cans are tightly packed.

Various modifications and changes are contemplated and may be resortedto without departing from the function or scope of the invention.
